Hi Linah . Please can you send me an estimate quote to do maintainance on my installed sandwhich extentions . I have approx 20 sandwhiches which I will replace as needed with your great lengths/ Keiro ( I have hair talk extentions at the moment which re exactly the same )I am just traveling to far to have them done . I also have half/ full head highlights with maintanance every 4-6 weeks. I look for ward to hearing from you soon. Kind regards Kathy.
